non-structural rhetoric elements 非结构性修辞元素
In calculating the seismic force of high-rise steel structures, the periods should be multiplied by a reduction factor (0.9) to account for the stiffness due to non-structural elements.
在计算高层钢结构地震剪力时， 周期应乘以0.9 折减系数以考虑非结构构件对刚度的影响。
The non-structural elements do not belong to the main structure, which can easily be ignored in the design and construction; earthquake will easily destroy the component and cause great harm.
由于非结构构件不属于主体结构，在设计和施工中很容易被忽视，使用中在地震作用下是很容易破坏的构件，它会造成巨大的危害。
